KOTOR was the first game since Halo that I rushed out to play. It's one of those games that you go and check release dates for every time you can to see if it is coming out any earlier than expected.
The many unique aspects of this game really made it a great gaming experience. The choice between light and dark, manually choosing how I wanted to speak, what missions I wanted and advancing my character's abilities. This game rocked and I've played it through 4 times. It doesn't get old in my eyes.
